Chapter 5 Connecting the Router to Power
Connect to AC Power
To connect the router to AC power, follow these steps:
Note
The router will power on as soon as it is connected to an AC power source. You are not required to press
a power button to power on the router.
Caution
When connecting the router AC power connector, always connect the router end of the cable first. When
removing the AC power connector, always disconnect the router end of the cable last.
Step 1
Turn off power to the AC power source at the designated circuits.
Step 2
Use a wire-stripping tool to strip each of the wires from the AC-input power source. Expose the wire to
the appropriate length for the terminal block, about 0.25 inches.
Step 3
Insert the wires into the terminal block openings that correspond to the labeled AC terminals shown in
Figure 5-1
and described in
Table 5-1
.
Insert wires that correspond to your installation (three-phase or single-phase), as shown here:
Step 4
After the wires are inserted in the terminal block, use the screwdriver to tighten the terminal block wire
screws to keep the wires in place. The screws are shown in
Figure 5-2
.
Step 5
Taking care not to place strain on the wires, insert the terminal block into the mating connector on the
router. The mating connector is shown in
Figure 5-4
.
Step 6
Use the screwdriver to tighten the two captive screws on the terminal block to the mating connector. The
terminal screws are shown in
Figure 5-2
. Torque the terminal block screws to 11 lbf-in.
Step 7
Turn on AC power by plugging in an AC power cord to the power source, or enabling power at the
designated circuit. The router will power on and run a series of bootup tests, indicated by blinking LEDs.
